Patent TW-283277-B (TW)
IPC: H03D3/00
Filed: 1995-03-14
Granted: 1996-08-11
Abstract: An automatic gain control (AGC) and D.C. offset correction method and apparatus for controlling signal power of a received RF signal within a dual mode quadrature receiver is disclosed herein. In a preferred implementation the automatic gain control apparatus may be adjusted to provide a desired control response to various fading characteristics of a received FM, FSK, GMSK, QPSK, or BPSK signal. The AGC apparatus includes an adjustable gain amplifier having an input port for receiving an input signal, a control port for receiving a gain control signal, and an output port for providing an output signal. A quadrature downconverter coupled to the output port serves to translate the frequency of the output signal to a baseband frequency, thereby producing baseband signals. In a preferred implementation the downconverter is operative to map the carrier frequency of the output signal to a baseband frequency offset by a predetermined margin from D.C. Two high gain active lowpass filters provide out-of-band signal rejection for the baseband signals. A D.C. feedthrough suppression loop, disposed to receive said baseband signal, suppresses D.C. offsets produced by the downconverter and lowpass filters, hence providing a compensated baseband signal. The AGC apparatus is further disposed to generate a received power signal based on the power of the output signal. A saturating integrator compares the received power signal to a reference signal and produces the gain control signal by integrating or by refraining from integration based on values of the reference, received power signal, and gain control signals, thereby extending the usable dynamic range of the receiver for FM mode.

Title: A method to incorporate non-volatile memory and logic components into a single sub-0.3 micron fabrication process for embedded non-volatile memory
Inventor: CHANG SHANG-DE TED
IPC: H01L27/10
Filed: 1998-02-20
Granted: 1999-10-01
Abstract: A semiconductor fabrication process allows for the fabrication of high-voltage transistors, logic transistors, and memory cells where, as required for sub-0.3 micron device geometries, the gate oxide of the logic transistors is thinner than the tunnel oxide thickness of the non-volatile memory cells without the undesirable contamination of the gate oxide of the logic transistors or contamination of the tunnel oxide of the memory cells. In one embodiment, the tunnel oxide of the memory cells is grown to a desired thickness. In a next step, a layer of doped polysilicon which will serve as the floating gate of the memory cell(s) is immediately deposited over the tunnel oxide of the memory cells, thereby protecting the tunnel oxide from contamination in subsequent masking and etching steps. The gate oxide of the logic transistors and the gate oxide of the high-voltage transistors are then grown to a desired thickness.

Title: Integrated circuits and manufacturing methods
Inventor: ILG MARTTHIAS
IPC: H01L21/316
Filed: 1998-03-25
Granted: 2000-06-11
Abstract: A method for planarizing a semiconductor structure having a first surface region with a high aspect ratio topography and a second surface region with a low aspect ratio topography.  A flowable material is deposited over the first and second surface regions of the structure.  A portion of the material fills gaps in the high aspect ratio topography to form a substantially planar surface over the high aspect ratio topography.  A doped layer, for example phosphorus doped glass, is formed over the flowable oxide material.  The doped layer is disposed over the high aspect ratio and over the low aspect ratio regions.  Upper surface portions over the low aspect ratio region are higher than an upper surface of the flowable material.  The upper portion of the doped layer is removed over both the first and second surface portions to form a layer with a substantially planar surface above both the high aspect ratio region and the low aspect ratio region.  The method is used for filling gaps, such as gaps between adjacent gate electrodes formed in a gate electrode surface region of a semiconductor structure.
